My interpretation: The Empress sits cradling stalks of wheat in her arms, a symbol of Mother Earth’s great bounty. Her belly is swollen with child, indicating a new life that is taking form. Your answers may concern that which has already come to pass (the wheat which is already grown) or that which is to come (the child growing in her belly) – and she challenges you to figure out which are the answers you truly seek.
Interpretation in the book: So you find yourself faced with a clear, if challenging, answer. You are in a position to nurture something. You must give enough of yourself to sustain life but not enough to smother the unique personality of the person, project, relationship, or situation you find entrusted to your care. – From A Guide to Mystic Faerie Tarot by Barbara Moore.
I don’t know. Myself I have never found anything that indicates nurturing in any of my decks when looking at the Empress. She has always represented things finished (the wheat sheaves she cradles in this card) and things still coming (the child she carries).
